The location and tracks were discovered by archaeologist Mary Leakey in 1976, and were excavated by 1978.
Based on analysis of the footfall impressions "The Laetoli Footprints" provided convincing evidence for the theory of bipedalism in Pliocene hominins and received significant recognition by scientists and the public.
For gait Tuttle looked at the step length, stride length, stride width, and foot angle, and determined that A.
afarensis was more human-like in gait than ape-like. afarensis is an obligate bipedal hominin with the beginnings of sexual dimorphism attributed to its species, and brain size very similar to that of modern chimpanzees and gorillas.
This conclusion is based on the reconstruction of the foot skeleton of a female A. White and Gen Suwa of the University of California, as well as detailed footprint analysis by Russel Tuttle of the University of Chicago; he compared human and other bipedal animals such as bears and primates, including gaits and foot structure, and taking into account the use of footwear.
With the footprints there were other discoveries excavated at Laetoli including hominin and animal skeletal remains.
